Cataracts and Cataract surgery

Your eye has a natural, clear lens that focuses incoming light into images at the back of the eye. A cataract occurs when this lens becomes cloudy, disrupting your vision and affecting your ability to perform everyday tasks comfortably and safely. Dr. Mark Hornfeld is an ophthalmologist offering glaucoma treatment and treatment for cataracts in New York City, including corrective eye surgery and intraocular lens implant options to restore clear vision, comfort, and quality of life.

Causes of Cataracts

Cataracts may form in the lens of the eye for many reasons. Understanding the causes of cataracts can also help you understand your risk for developing them and the related vision problems they cause.

  1. The most common cause of cataracts is the natural aging process. Studies indicate that 70% of individuals age 75 or above have cataracts. Risk factors for cataracts such as diabetes, blood pressure, and long-term exposure to sunlight may also increase as you age.
  2. In some cases, cataracts can be caused by traumatic injuries that affect one or both eyes. A traumatic cataract may form soon after an injury, or it may develop many months later.
  3. Some cataracts are present at birth or develop during early childhood. Congenital cataracts may be either hereditary or linked to other types of birth defects.

Cataract Surgery and Intraocular Lens Implant Options

Because cataracts cloud the natural lens of the eye, corrective eye surgery to address cataracts replaces the damaged lens with an artificial one to restore clarity of vision. Intraocular lens implants are available in a variety of styles to eliminate cataract symptoms and often provide intrinsic vision correction if you suffer from nearsightedness, farsightedness, or astigmatism.

  • A monofocal intraocular lens provides clear, corrected vision at a single distance: near, intermediate, or far. You can choose the distance at which you want your lens to correct your vision; you will need to wear corrective lenses, such as glasses or contacts, for clear vision at other distances after your cataract surgery.
  • A multifocal or accommodative intraocular lens functions more like the natural lens of your eye, providing corrected vision at multiple distances. This reduces or sometimes eliminates the need for corrective lenses following surgery.
  • If you suffer from astigmatism, a toric intraocular lens provides monofocal vision correction as well as astigmatism correction due to its unique shape. You may or may not require corrective lenses after cataract surgery, depending upon your eye's characteristics.
